This invention relates to improvements in weatherstrips, and more specifically to that type of metal Weatherstrip adapted to be received between the window frame and the window sash so 5 as. to prevent the passage of air, dust, rain, and snow between the frame and sash, as well as to co-act to prevent rattling of the sashes.

One of the objects of the invention is to provide a metal Weatherstrip of the character mentioned which provides novel means of rigid and permanent attachment to the window frame.

Another object of the invention is to provide a Weatherstrip which may be positioned in the sash runways between the sash stile and the j amb and which may also be positioned intermediate the space between the parting strip and the face of the sash stile in those cases where the construction and installation of the sash balance will not permit convenient installation of the weatherstrip in the sash runway.

With these and other objects in view, the invention resides in the features of construction, and arrangement of parts which will now be described, reference being had to the accompanying drawing, in which- Figure 1 is a fragmentary horizontal sectional view of a window frame and upper and lower sashes equipped with my invention, the weatherstrips being shown positioned in the sash runway intermediate the sash and the window frame jamb;

Figure 2 is a View similar to that shown in Fig. 1 illustrating the weatherstrips positioned between the parting strip and the faces of the sash stiles;

Figure 3 is an enlarged perspective view of a length of the Weatherstrip; and- Figure 4 is a fragmentary horizontal sectional view of a window frame and sashes illustrating a modified form of attachment of the weatherstrip, the attaching end being received within a vertically extending kerf appropriately provided in the parting strip.

Referring to said drawing, Figure 3 illustrates a section or" a length of metal Weatherstrip, preferably formed from copper, or other appropriate non-corrosive material. The strip is so shaped in cross section that it provides a plane surface 2 of comparatively narrow width between the opposite longitudinal edges of the strip, one of said edges being bent to form a longitudinally extending L-shaped depressed portion 3, said depressed portion being located below the level of the general plane of the strip. The width of each 5 leg of the angle forming the depressed portion 3 is substantially identical with the width of the plane surface 2.

The longitudinal edge of the strip opposite the depressed portion 3 is rolled or curved upwardly to form a. longitudinally extending sash-contacting ridge 5.

Installation of the Weatherstrip is accomplished in a manner readily understood by a study of Figs. 1 and 2 of the drawing in which a is the jamb of the window frame; I and 8 the upper and lower window sashes, respectively, and 9 the parting strip, the latter having its inner vertical edge reduced in size to provide two opposite right angle shoulders. Obviously, the parting strip is received within a conformably shaped channel provided in the jamb 6, the strip being embedded in the iarnb to a point where the offset shoulders occupy a depth beneath the face of the jamb equivalent to the width of one of the legs of the depressed portion 3.

As shown in Fig. l of the drawing, each of the pair of strips required to Weatherstrip the two sashes is permanently held in position by locating the depressed portion 3 within the channel of the jarnb adapted to receive the parting strip 9 in such manner that the free leg of the depressed portion (the leg parallel with the plane portion 2) is received behind the offset shoulder of the parting strip. Thus, when the parting strip is nailed in place, each Weatherstrip will be rigidly held in position thereby. As explained in the brief description of the drawing, in Fig. l the ridge 5 occupies a sash contacting position intermediate the sash runway and the edge of the sash. This arrangement is possible in cases where the sash balance elements are not located in this space and, therefore, do not interfere.

In some instances, however, sash balance mechanism is utilized which occupies the space between the sash and its runway, in which event the invention is positioned as shown in Fig. 2. Where this situation is encountered, the strips are positioned in such manner that the curved roll 5 contacts the face of the sash stile and lies between such face and the parting strip 8, the Weatherstrip being hidden behind said parting strip. In this mode of attachment, the angle leg of the depressed portion 3 not parallel with the plane portion 2 is received behind the offset shoulder of the parting strip while the other, or free, leg extends on inwardly into the rabbeted portion of the channel in the jamb.

In the modification depicted in Fig. 4 of the drawing, the parting strip I0 is provided with an appropriate longitudinally extending kerf [2 of a size in cross section sufficient to accommodate the depressed portion 3 in either of the aforesaid two positions.

It will be understood from the foregoing description that the construction of Weatherstrip described is easily, conveniently and permanently attached for effectually preventing passage of air, snow, rain, etc. interiorly of the window. Moreover, it will be understood that the Weatherstrip is adapted to fit either the upper or lower window sash in either of the two sealing positions hereinbefore described.

Minor changes in shape, size and arrangement of details coming within the field of the invention claimed may be resorted to in actual practice if desired.

What is claimed is 1. In a window frame, the combination of a jamb having a channel to receive a parting strip, said strip having a longitudinally extending 01T- set provided therein at a point below the surface of said jamb, of a metal Weatherstrip having a plane surface of a width substantially equal to the distance between the surface of said jamb and the oiTset of said parting strip, another portion of said strip at one side of said plane surface being bent to form a pressure edge, and another portion of said strip at the other side of said plane surface being bent at an angle to said plane surface to form fastening means conformably engageable with the ofiset of said parting bead, said plane surface of said Weatherstrip being adapted to be disposed between the parting bead and the jamb so that the pressure edge will contact the face of a window sash between the latter and the parting strip, and said plane surface also being adapted, when desired, to be disposed between the jamb and the window sash so that the pressure edge will contact the edge of the sash intermediate said sash and its runway.

2. In a window frame, the combination of a window frame, a sash, a parting strip provided with a longitudinally extending shoulder at a point between its inner and outer edges below the surface of the window jamb, and a weatherstrip having one of its longitudinal edges bent to form a pressure edge and having its opposite edge bent into substantially Z-shape in cross section, the center leg of the Z-shaped edge being adapted to be conformably received by the shoulder of the parting strip when the pressure edge is to contact the face of the window sash, and the free leg of the Z-shaped edge being adapted to be conformably received by said shoulder when the pressure edge is to contact the edge of the sash adjacent the jamb.
